Review Detail of Yamette_Kutasai in DxD: The Dragon Oppai

Tldr, this fanfic feels extremely similar to another dxd fanfic in fanfiction.net I've read: The delinquent dragon emperor. It has been a while since I've read the fanfic (2 - 3 years ago), so there should be a couple of details that I've missed, but I still remember the general plot line and setting are extremely similar. Including female Vali and Tiamat visiting Kuoh. On another note, I fail to understand why the title is Dragon Oppai, since this Issei is not exactly perverted o.o Well, I just hope this isn't what I think it is. I'll continue to read it in the future, but I'll drop it for now since I was looking for a normal issei fanfic.
